6.5 meat and fish production
fisheries/aquaculture harm aquatic enviro
overexploitation
toxins
heavy metals
PCBs
dioxins
CO2
1.5 units of energy/1 unit of food
1/3 of fish for farmed fish/livestock
fish oil
fishmeal
bottom trawling
nets destroys seafloor habitat
probs
large amounts of waste=eutrophication
habitats destroyed for fish farms
farmed fish contaminated by pesticides
fish fed antibiotics
damage ecosystem
promote antibiotic resistance
meat production
3 most consumed
pork
poultry
chicken
turkey
beef
1950-2014 production 6x
animal food cheaper
higher yields due to industrialized farming
improved transport
higher per capita incomes
nations in industrialization
UN food & agriculture org. (FAO)
consumption 2x by 2050
industrialized meat
50% meat
rangelands
pastures
50%
feedlots
outdoor intense feeding
factory farms
buildings of crowded pens and cages
mass production
green revolution
more food=no pasture needed
grain

growth hormones
enter human body
health risk
antibiotic resistance
industrialized fish
fishery
concentration of a particular species for commercial harvest in a body of water
aquaculture/fish farming
raising fish for sale
FAO
87% of fisheries harvested at full capacity
57% overfished
industrialized production meat harms enviro
huge amount of agriculture
habitat destruction
overgrazing
water consumption
water used to irrigate crops for livestock
1 burger=1700 lbs water
water pollution
livestock waste washed into waterways
eutrophication
pollution
antibiotics
hormones
pesticides
climate change
meat production=greenhouse gases>all cars
methane released as cows feces
produce food sustainably
reduce desertification
spread feeding/watering areas
crowds dont turn areas into mud=soil erosion
no feeding antibiotics/hormones
use waste as fertilizer/biogas
eat line caught fish only
1 meatless day/week
=30-40m cars off road/yr
